Adobe Flash Player 24.0.0.186 Installing via SCCM but some clients get pop up to install Flash Player

I pushed the active X and NPAPI msi of Adobe Flash Player version 24.0.0.186 (released 12/13) via SCCM. It successfully installed on most of our clients.

I'm now seeing an issue where a few clients are getting a pop up asking if they want to install Flash Player even when SCCM and Programs & Features both show it (24.0.0.186) already installed on the client.

We went from 23.0.0.207 and jumped to 24.0.0.186. Is there a requirement to install a base version of 24 perhaps 24.0.0.1? I'm just trying to determine why some clients see they have 24.0.0.186 and others are acting like they need Flash Player installed.

I deploy mine the same way and never ran into this issue. But I also make sure I disable the Flash auto-updater by copying mms.cfg to C:\Windows\System32\Macromed\Flash\ and C:\Windows\Syswow64\Macromed\Flash\ with every deployment (using the script type and the .EXE installer rather than the buggy .MSI package Adobe provides). The MMS.CFG file contains the following 2 lines:

AutoUpdateDisable=1 SilentAutoUpdateEnable=0

and the file is saved using UTF-8 encoding (important as it otherwise does not appear to work right). The Flash installer is ran using the "-install -force" parameters to force a silent install and ignore any newer versions detected (long story).
